Hi Oueslati

Scout Classic requires a Java UI Server on the backend, thus the UI cannot run without a connection to the backend. Scout Classic provides some limited offline Features, like allowing the user to enter text in a text-field while offline. But there's no extensible concept to run business logic while you are offline.

If you must have offline support, you should use Scout JS where everything runs in your browser. Scout JS enables you to build apps that run without an online connection.

You can also mix the two Scout flavors. If you have an existing Scout Classic application, you could embed a Scout JS app for a specific offline purpose (e.g. an OfflineAppForm). Technically this should work, but I have no simple example to show you. Also Scout JS requires you to provide your own HTTP services (like REST) in order to load/store data. You cannot simply re-use the Scout Classic protocol for your Scout JS app.

Cheers, André
